Fix T95666: Crash when attempting multires linear subdivide

The crash was happening when the mesh had loose edges.

Loose edges are not part of OpenSubdiv topology and hence should not be
communicated to the refiner. Pass ta boolean flag indicating whether an
edge is loose or not in the mesh foreach routines, which seems to be
the easiest way.
